 |
|
I've got a simple question that probably has a simple answer. What is the difference between using && and ; to seperate commands in the CLI?
I tried searching google and these forums, but && and ; are hard to search for 
Thanks. |

| Code: | $ false; echo "hello"
hello
$ false && echo "hello"
|
";" will execute the next statement even if the first one fails. "&&" will only execute the next statement if the first one returns successfully. |

There's another one also, "||" will execute the second statement, only if the first one fails:
| Code: | $ false || echo "hello"
hello
$ true || echo "hello"
